| 摘 要： | 发动机氧泵至燃气发生器段的流场结构直接影响着发动机的工作性能,从理论上分析氧泵后是否需要设置整流栅以调整流场,对发动机总体设计十分必要。针对氧泵后流场的特点,借助CFD计算手段,对该段流场进行有整流栅和无整流栅两种情况的数值模拟,计算得到流阻、发生器入口处的总压均匀度、氧阀流量均匀度以及阀芯受力情况。结果表明:氧阀后设置整流栅是有必要的。

| Abstract: | Effect of the flow field structure on the performance of the engine. It is important to structure parameter design of engines that set up perforated distribution plate to adjust the flow field. Use CFD to simulate flow field, and total pressure uniformity, Oxygen valve rate of flow uniformity and stress condition of valve spool. Result can provide reference for the design and optimization of assembly line. |
